UM7 Orientation Sensor

UM7 Orientation Sensor

The UM7 is a 3rd-generation Attitude and Heading Reference System (AHRS) that takes advantage of state-of-the-art MEMS technology to improve performance and reduce costs. Like its predecessors, the UM7 combines triaxial accelerometer, rate gyro, and magnetometer data using a sophisticated Extended Kalman Filter to produce attitude and heading estimates.

How To Buy

Overview

The UM7 is a 3rd-generation Attitude and Heading Reference System (AHRS) that takes advantage of state-of-the-art MEMS technology to improve performance and reduce costs. Like its predecessors, the UM7 combines triaxial accelerometer, rate gyro, and magnetometer data using a sophisticated Extended Kalman Filter to produce attitude and heading estimates.

The UM7 also adds many new features, including higher gyro bias stability and lower noise, a new communication architecture for improved flexibility, optional NMEA packet transmission, UTC time-synchronization with external GPS, and support for third-order temperature compensation on all sensors.

Even with its added features, the UM7 is offered at a significantly reduced priced compared to other sensors in its class.

A USB Expansion Board is available to make it easy to connect the UM7 to your computer. You can then use the CHR Serial Interface (available in the “Resources” tab) to configure the sensor, and view and log data in real-time.

The UM7-LT is equivalent to the UM7, except that it does not include an enclosure and factory calibration is not available. The UM7 is a 3rd-generation Attitude and Heading Reference System (AHRS) that takes advantage of state-of-the-art MEMS technology to improve performance and reduce costs. Like its predecessors, the UM7 combines triaxial accelerometer, rate gyro, and magnetometer data using a sophisticated Extended Kalman Filter to produce attitude and heading estimates.

Extra cable assemblies for the UM7. The UM7 comes with one 5-pin cable assembly for the main IO header. Additional cables are not needed unless you want extras, or you want to use the 6-pin IO expansion headers.

The GP9 has been discontinued and is no longer available for purchase. The GP9 is a GPS-aided AHRS that measures orientation, velocity, and position at 500 Hz. The GP9 combines temperature-compensated rate gyros, accelerometers, magnetometers, and absolute air pressure with GPS to produce angle estimates that are reliable even during aggressive dynamic maneuvers. Unlike more simple attitude sensors, the GP9 is capable of measuring its yaw angle without relying on unpredictable magnetic field measurements.
